Hello
I found myself in a curious situation regarding the state of a zpool inside
a VMWare Guest. I've run into CKSUM errors on the below infastructure
stack.
> Hitachi (HDS) 9570V SAN, FC Disks
>> SUN X4600 M2 (16 Core, 32GB Memory)
>>>> VMWare ESXi 3.5 U3
>>>>> Single Extended Datastore, 4x 35GB FC LUNs.
>>>>>>>> Solaris 10 u6 x86 Guest OS
A striped zpool on the Solaris Guest is starting to show some CKSUM
Errors. This is very surprisingly by itself because of the Enterprise
hardware we're dealing with, but assuming we can ignore why these errors are
happening for the time being: How do I diagnose the state of the 'apps'
zpool?
1. Why is ZFS showing <0x0> instead of an actual file(s)?
2. How do I see where/which files these CKSUM errors are affecting?
I'm not seeing *any* errors or warnings in messages.
Any thoughts?
# zpool status -v
pool: apps
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.
